IMPROVED ROLL POR PELTING 0R SIZIIIGIHAT BODIES BY MACHINERY.

SPECIFICATION.

IO ALL WHOM IT MAY4 CONQERN: d o

Be it known that I, I HILIP W.y SoMnns, Vof Danbury, in' the county of vFairfield, and State of Connecticut, have invented a certain new andimproved'Roll for Felting or Sizing in Hat Bodies in `the roll, byMachinery;` and I do hereby declare that the following is a full andcorrect description thereof, reference being had to the annexeddrawings, making a part of this specification, and to the letters ofreference thereon.

.My said invention consists in an improved roll, in which the coils orfolds of the bat or bats, rolled up i Within the covering cloth, are ina reverse direction from the coils or folds of the covering orenveloping cloth. y

Hitherto rolls have been made up for machines the same as for the handprocess of sizing; that is, the coils of the rolled bats or bodieswithin the enveloping cloth run in the same direction as the coils ofthe enveloping cloth,

and, although machines of various kinds have been devised to work therolls for the purpose of sizing them in,

they have hitherto failed to take the place of the hand-wnrking, for thereason that the bodies thus rolled and worked do'not shrink in thedirection designed by the ha'tter when making up his roll; and also,because they are inferior in quality to the hand-worked bodies. But inthe use of my improved roll, above described, these difficulties do notoccur, and hat bodies can be practically sized in, by working them inthe roll,` in machines which carry the roll or rolls continuouslyforward, either by a simple rolling motion, or by a compound forwardmotion i having a jiggering action involved with it,r as in mostmachines heretofore patented. I have no certain knowedge of the reasonwhy reversingthe direction of the coils of the rolled bodies withrespect to the coils of the" covering cloth produces so great adifference in the result of the operation of linachinery upon the libresof the p bats constituting the hat bodies, but believe thatiwhen the,bodies are submitted to the action of machinery in my improved roll,the fibres receive motion and pressure in the same direction as they dowhen subjected to the i hand process in the form of rolls commonly used.I have observed that when a hat body in the roll with the enveloping orworking cloth is rolled on a table, under pressure, that the coils workor move inone direction or its opposite, according to the direction inwhich it is being rolled under pressure. Those acquainted with the reration of machinery used, or attempted to be used, in working hatbodies in the roll in the process of sizing, are familiar with the factthat the rolls have to be p ut into the machines in such direction thatthe enveloping cloth will be rolled up and kept rolled up underpressure, otherwise the enveloping or working cloth would be r `.rolled`or stripped from the bats constituting the hat bodiesytheimachineclogged up, or the bats ruined. `)Let this isV precisely the oppositedirection from that in which motion with pressure is usually applied tothe same rolls by the hand process, wherein the motion under pressure,during the greater partof the time, isrin a` direction away from thebatter, unrolling the covering cloth to the extent of that motion,theroll being restored b'y the batter rolling it lightlyback towardshim; it being a necessity in the operation of continuous machines on hatbodies in the roll to keep rolling the,rolls under pressure in adirection that will keep the covering cloth i cftherolls rolled up,which is the contrary direction from the direction in which the greatestpressure and ino tion are applied by hand. I have sought to remedy thediiculties experienced inwerking rolls by machinery i by reversing thedirection of the coils of the bats within the covering or felting cloth,with respect to the covering cloth, and by this means I am enabled tokeep the rolls rolled up in the machine, and yet get the good result lof hand sizing. My new roll may be most conveniently made by rolling upthe body or bodies toward the haty .l old roll, and then turning theroll end for epd before rolling i't up in the cnvelopter, as is usual inmaking the ing or working cloth, which is t batter as usual; thereversal being effe A the roll than turning the roll of the body orbodies end for end before rolling it up in the cloth. The roll may,

however, be made by rolling up the body or bodies towards the hatter onthe working cloth, and then rolling the working cloth around theroll ofbodies by rolling from the batter without changing` the roll of bodies`end for end, as when the roll is made by rolling both the bodies andworking cloth towards the batter. But the latter mode of operation isnot in accordance with the usual practice of hatters, which is to rolltowards them, and

hen rolled around therollof bodies in a reverse direction, by rollingtowards the therefore not so convenient. I o

The drawing, Figure 1, shows an end view of a hat body andcoveringcloth, rolled for the' hand process of sizing, with the coil aof the hat body in the same direction as the coilsb of the workingclot-h. y o

An end view of my new reverse roll is shown at Figure 2 of the drawings,the coils c ofthe `bodybeing in a reverse direction to the coveringcloth d.

cted vwithout other change in the manipulation of the batter in making yAlthough my new roll can be Worked to better advantags than the old rollin machines having a vibrating or jiggering motion combined with aforward motion, such machines are not adapted to produce the bestresults by reason of the reverse rolling they give the roll underpressure, and therefore I have devised certain improveo. ments inmachinery for working my new rolls, embodied in a. machine described ina separate' application for Letters Patent, which isnot suitable forworking the old roll.

I claim, as my invention and improvementi The new roll adopted forWorking hat bodies in the roll by machinery, wherein the coils or foldsof the body or bodies rolled up within the covering cloth are in reversedirection from the coils or folds of the covering cloth,

substantially as and for the purposes hereinbefore Sei forth.
